Poor idle on start up
Experiencing a poor idle on start up on my 2WD Stage 3 Saph.
It's not even related to being just when cold. If started when warm it often still dies instantly when the throttle isn't held.
Any ideas?

It is running a lot lower boost than it should for stage 3 at the moment, this maybe add to the problem? Was set up previously for the proper amount, so maybe running rich because of that?
ooops, just noticed this is in the Escort page rather than Sierra one! Feel free to move it mods!

More boost Igor!

Only way to tell if it is actually rich is to stick a lambda probe up its arse, and then the CO should be adjusted to the chip author's specification (but certainly below 3.5% at MOT time).
Idle mixture is mainly goverened by the coolant temperature, fuel pressure, and CO pot setting. If it's had the fuel pressure raised for "more power" (see if the tamperproof plug's still on the regulator) it'll be rich all over the shop. Best thing to do is get a basic setup done so that idle speed, boost pressure, fuel pressure and CO etc are all set properly.

My escos does this but only when its hot, i need to keep it above 1500rpm for about 5 seconds or it just cuts out. The base idle screw on mine is siezed solid so i cant see if it makes a difference, i dont think it would though as it ticks over fine
